摘　　要：潜艇使用自航式声诱饵防御声自导鱼雷是水下防御的主要手段之一,传统穷举统计方法计算量随决策参数增多而急剧增加,无法满足实时性要求。从基于多实体有限状态机的鱼雷防御模型出发,提出了2级并行策略,在进程和线程间划分仿真循环,通过数据交换作出最优决策。实验结果表明,并行后的模型可以在短时间内作出和实际作战情况相近的决策,在404个方案仿真的计算量下,模型运行时间从144.65 s缩短至1.2 s,获得了120倍的加速比,有效解决了实时方案决策的问题。One of the main means of underwater defense is to use self-propelled acoustic decoy to defend the acoustic homing torpedo.The calculation amount of traditional exhaustive statistical method increases rapidly with the increase of decision parameters,which cannot satisfy the real-time requirements.According to the torpedo defense model based on a multi-entity finite state machine,this paper proposes a two-level parallel strategy,which divides the simulation cycle between processes and threads,and makes the optimal decision through data exchange.The experimental results demonstrate that the parallel model can make decisions identical to the actual combat situation in a short time.Under the calculation amount of 404 schemes simulation,the running time of the model is shortened from 144.65 s to 1.2 s,120 times faster than the original program,which effectively solves the dilemma of real-time scheme decisions.
